Zh a/ZZ whom it mctyvc'ocem: 1 4 Be it known that LGODFREY NEUEN-` SHCWANDER, of Louisville,ifn the county of VJefferson and State of Kentucky, have in- .vented a new and Improved Windowlind, Vof which the following is a full, clear, and

exact description.

f My invention relates to an improvement in window blinds, especially to that class of blinds known as Venetian or slat blinds, and

vtheobject of the invention is to so construct 'the blinds that they may not only be rolled up but may be so placed as totorm an awnling. waterproof and sunproof';ar 1danother objectjof the invention is toconstruct the blinds in such a way that the upper portion may be rolled up exposingthe'upper section of the'window while the lower portion of the A V,window inay be closed or concealedl by the lower section of the blind., Another object of the invention isto'constructa blind possessing theabove character# istics which will beAv exceedingly simple,jdu

'. f struction and combination of the several .parts, as `will be hereinafter full `'rablefand economic. t

-jThe inventionconsists inthe novelconfand pointed out inthe' claims. Y lReference is to be had to the accompanying drawings, forming a part of this specification,

ence indicatecorresponding parts in 'all the"` Views. I "7 Figure 1 is aninnler face'view of the improved blind,iillustrating itas closing the en-4 tire window, Fig. 2 is a sectiontaken substantiallyon the line2-' -2 of Figol, th'e blind being -partiallyelevatedg Fig. is a section taken substantially on the line 3--3 of Fig.V 1, in

which the blind-is 1n position to form an'awnf '1 ing. Fig. 4 is afhorizontal section taken substantially on the .lined-4 of Fig. 1., vFig.'5

is a detail inner faceyi'ew of a portion of the' blind; and Fig. 6 is a'n'edg'eview of the same. '45` plocated at eachside of the outer face of the fIn carryihgout theinventiona rail 10 is window ffrarne Afand each rail is preferably l made wideratthe Vtopthan at any othenpoint L 0inits lengthL'and the-upper portion'of the: -59

tworails is-,connected by a hood or housing which in turn is ordinarily protected by av yf'set forth,

housingor h ood' 12 secured to the building. lEach rail' is made in two or moresections,`

shown in Fig. 5,wherebyupon removing the' pintles b2 the sectionsof therail may be seprated,lifdesired. vEach rail sectionv atits and l5, and the cross jbars ofthe lower 'rail sections as V16 and 17. .Eachral is furthermore provided upon its inner facewitha lon!A gitudin'al groove 18, extending virtually from the top to the bottom.v

lnsuitablehangers attached for example to the outer sidesof the window frame, a rollerjl 19 is journaled, turning loosely inthe upper .the said roller is usually provided at one end "with a sprocket wheel 20, over which aA link belt 2l ispassed, the said belt being passed,

it \is passed yat 'its lower end over a sprocket -wheel 23) the-said sprocket wheel beingsfast ufpon a spindle 24,(the said spindle being' like- `Wise provided withva gear 25, controlled bya pawl 2.6, the said 'gear being made to mesh with a pinion '27, Qp'eratedthrough Athe medium of a crankarm 28-.' T hus by turning the crank Iarm 28 the roller 19 will be revolved in a direction to wind-the Abli-nd4 thereon, or permit theblindto unwind therefrom. The rail sections -are held in place,1that is, in vertical'` or their'equivalentsattached either to thesections of the rails and engaging withethe wininwhch latter event theyengage with the rails.,"-

passed through' the'knuckles and-screwed into'one section of .the hinge, as is likewise abutting end isprovided with two cross bars, l an inner and an outer one,`the cross bars ot t `the upper rail sectionsgbeing designated as 14 Y ends ot the rails 10;' The roller ,19 has at-v tached-to it thenppex; end ofthe blind B; and

inwardovergui'de rollers 22, and downward along the inner face ofthe window frame, and

alignment, through the medium of hooks29 dowframe, or attached to thetwi'ndow frame,

I C O The slats 30 of the blindlarenadeto overone of such hinges being located at each side order that the lower rail sections may travel v upward readily they are provided at their.

entirely upon the roller.

near each end of the series of slats and upon the inner face thereof, the joint being made `in the hinge wherever the two slats overlap;

and at predetermined slats, below the cross` bar 17, removable pintles 33 are placed in the knuckles of the hinge, whereby upon removing said pintles the blinds will be in two sections, one independent of the other. y

The blind, when lowered, travels inthe grooves 18 in the rails, and the rails may be raised to form an angle moreor less acute, as shown in Fig. 3, by attaching to t-he lower ends of their end sections cables 34, as shown in Fig; 3, carrying the said cables upward over suitable guide rollers 35, and downward along the inner face of the window frame, the cable being provided for example with series of loops 36 adapted to be passed over keepers37. Thus by drawing downward upon .the cable 34 the lower section of each of the rails will be raised,land the upper section will be'carried oitward,-the two sections forming with1 n the framesubstantially a triangle.

At that time the blind is wound partially, or almost Now by unrolling theI blind it will drop from the grooves in the `upper sections of the rails vertically down-` ward, forming, as shown in Fig. 3, an awning, serving as a protection from the weather and from thesun, the awning being raised or lowered'by theadjustment of the rails; and in lower ends'wi'th friction rollers 38..

y When the two sectionsof the blind are separated, and the upper one wound upon the roller, the lower blind section is heldin place preferably by causing screws 40,. located in `[suitable bearings 41 placed upon the inner of theslats below that whose hinge is provided faces of the window frame,to` enter-'plates 4:2, laced for example upon the vinn/er face of one with a removable pintle 33,:a`s shown in Figs.

l and4. 4It will thus be observed that an lawning blind may be vconstructed capable of use in car windows, or in connection with the windowseof dwellings, `orin fact any structu ure, whereby an awning may be expeditiously randconveniently formedfrom the blind, and

the blind as readily 'restored to whatmay be x termed its 'normal position. y

. Having thus described my `1nventio,n ,`-IN

claim as new and desire to secure by Letters Patent- 1. In a Window blind` the combination with a blind, and means for raising'and lowering the same, of a guide for the blind at each side of the window, said guide being hingedat its upper end and formed of sections hinged together, substantially as and for the purpose set forth'. y

' 2'. In a window blind, the combinationwith a roller, and a blind adapted to be Wound on the roller, of a guide for the blind at each side of thewindow, the said guides being formed of hinged sections, the uppersections of which are hinged to the window frame, whereby the lower sections may be raised4 and the upper section carried outward, substantially as and for the purpose set forth.

' 3. In a Window blind, a rail hinged at its upper end and divided Yinto hinged sections, a roller, a slat blind carried by the roller and guided by the rail sections, and means, sub' stantially as described, for raising the lower sections of the rails, as an for the purpose set forthJ 4. In a'window blind, the combination, with rails 'pivoted at one end to the window frame, the said railsbeingprovided with guide ways and constructed in hinged sections, whereby the lower sections of the rails may be raised and the outer sections carried outward, 0f a roller, means, substantially as described, for

rotating the said roller, a slat blind attached to the roller, adapted to move in the guide ways of the rail, and means, for' elevating the forth.

archer, of a sla't blind carried b'y the roller,

y lower rail sections, as and for the-purpose'set` IOO the slats of the blind being connected ,by hinges, sundry of which are separable, 'and I 'means for locking the lower section of the blind in place when separated from the upper-section',substantially as described. J

- 6. Inawindow blind,the combination, with guide ways, a roller and a slat'bliud carried Q by the roller and traveling in said guide ways,

.the slats being connected by continuous hinges,.s undry of the knuckles ofA which are provided'with removable pintles, of sockets located upon sundry of the slats,and locking devices adapted for attachment to a window frame, and likewise adapted to enter `the said sockets, whereby' the blind may bei' divided `Set.forth.r GODFREY NEUENSCHWANDER.
